Hello,
Can you provide the footprint / MPN of the specific USB-C receptor and microSD used in the SparkFun Thing Plus - STM32?
Also, I notice no ESD protection chips are used. Can you explain why it is not necessary?
Thanks!
Here’s the board dimensions https://cdn.sparkfun.com/assets/d/5/9/5 … utline.png , here are the .brd and .sch files https://cdn.sparkfun.com/assets/5/0/a/b … _Files.zip and here’s the datasheet https://cdn.sparkfun.com/assets/4/c/b/0 … 851084.pdf (our internal part # is DEV-17712)
The inclusion of ESD protection/not is usually a a function of the item’s cost
